in Integration and Hardware • 4 months ago

Hello there!!

I made a program using javaMail, and it works just fine in my machine...

When i try to run the program in other machines the program send me this error:

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25;

nested exception is:

java.net.ConnectException: Connection refused: connect

I moved the topic from Programming Questions because you don't show code, and it is a problem with export, not with your code.
I also deleted the answer you posted to the topic, not because you resurrected an old thread, but because it was duplicate with this one. It is better to start a new thread as you did, and to link to other threads if needed, as I did...

The error message is quite clear... For some reason, the SMTP server Gmail refused your connection. I don't think it is a firewall problem, as this port is quite common.
Mmm, perhaps the issue is that you connect on port 25, not secured. Maybe it is possible on your computer, because you are authenticated on it, so it is listed as OK, but on another computer, you are not recognized.
Also some mail servers want you to check you mail before sending a message, as another mean of authentication.

" you are awesome to thing that 32 lines of error were clear."
I read lot of stack traces at my work, so I know where to look...

The important parts are generally at the top of the trace, here the

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25;

nested exception is:

java.net.ConnectException: Connection refused: connect

part. I just glanced over the remainder...

" would it help for you to help me if i show you the part of the code that sends and authenticate the email ??"
I don't know. Each SMTP server has specific requirements, you have to follow them closely to make this to work. I don't know the requirements of Gmail. Have you tried the "read before sending" trick?

I'm afraid i did not tried the "read before sending", i don't even know what that means ... =(

Well, the big idea of my program is to make a series of questions and save the answers in form of points, then show a result based on the points you made.. after that it shows a screen asking if you want to restart the program or to send the report as an email...

And that is it....

Since you don't know the SMTP for Gmail by any chance do you know from any other??

I tried installing the processing and copping everything from my skech, updated the java to 7u21(the same in my machine). And nothing... It only work in here...

Look at the thread you dug out (and that I link to), I give a link to an e-mail sketch that works for me, for my SMTP server, using port 587 instead of 25.
But apparently you made it work, so you know already some of this stuff. Again, read attentively the Gmail instructions how to query and send mail with it, perhaps you missed a step.

" i don't even know what that means"
See above: " some mail servers want you to check you mail before sending a message"
